When I switch on my computer, I get the GRUB menu in very low resolution (640 x 480).



I would like to know how I can change the resolution of GRUB.



To get information about my current resolution, I applied the following (instructions from Marmayogi in this post):



  • Pressed "c" key to enter GRUB's command line grub> at start up.

  • Executed the following GRUB commands: grub> set pager=1 and grub> videoinfo to get the available screen resolutions and my resolution marked with a "*".

But I do not know how to actually change the resolution.



Things to take into account: I am using a Nvidia graphics card RTX 2070 and have installed Nvidia driver version 410, and I'm running Ubuntu 18.04.

Best to leave it set for 640x480. Setting it to any higher resolution just makes the GRUB menu tiny, and harder to view.



However, if you must change it...



sudo pico /etc/default/grub



Find:



#GRUB_GFXMODE=640x480


And change it to:



GRUB_GFXMODE=640x480


changing the resolution as desired.



sudo update-grub
